An overview of the concept of 'double' and 'near double' in the context of adding one-digit numbers. It explains the definition of 'double' as a number or amount that is twice as large as the given number or amount, and provides examples of doubling numbers. The document then introduces the concept of 'near double', which refers to a number that is close to a double, such as double plus 1, double plus 2, or double minus 1. Two activities where the learner is asked to solve problems related to doubling and near doubling of one-digit numbers. Overall, this document seems to be part of a lesson or educational material focused on teaching mental techniques for adding one-digit numbers, which could be useful for students in the early stages of their mathematical education.

Lesson 4 Adds Two One-digit number using appropriate mental techniques adding doubles and or near doubles What is double? Double is a number or an amount that is twice as large as the given number or amount. Examples 5+5= 20+20= 6+6= 7+7= So, if we multiply a number by two or if we add a number to itself.We say that the number is doubled. Let's take a few more examples doubling. 1 ball resu lts in 2 balls If we double the 2 pens,we will get 4 pens
Activity 1 Solve the problem below.
5+5=
3+3=
4+4=
2+2=
3+3=
What is near double A near double is a number close to a double .For examples,7+8 is considered a near double because it is a close to the double number 7+7.Near double could be double plus 1, doubles plus two or doubles minus one. Examples.
